kconfig: readd lost change count

2008-09-29T15:03:01+00:00

Commit f072181e6403b0fe2e2aa800a005497b748fd284 ("kconfig: drop the
""trying to assign nonexistent symbol" warning") simply dropped the
warnings, but it does a little more than that, it also marks the current
.config as needed saving, so add this back.

kconfig: drop the ""trying to assign nonexistent symbol" warning

2008-08-04T20:29:37+00:00

They really stand out now that make *config is less chatty - and
they are generally ignored - so drop them.

kconfig: set all new symbols automatically

2008-07-25T20:12:48+00:00

Add conf_set_all_new_symbols() which set all symbols (which don't have a
value yet) to a specifed value.

kconfig: explicitly introduce expression list

2008-01-28T22:14:39+00:00

Rename E_CHOICE to E_LIST to explicitly add support for expression
lists. Add a helper macro expr_list_for_each_sym to more easily iterate
over the list.

kconfig: rename E_OR & friends to avoid name clash

2008-01-28T22:14:38+00:00

We had macros named the same as a set of enumeration values.
It is legal code but very confusing to read - so rename
the macros from E_* to EXPR_*

kconfig: allow overriding symbols

2008-01-28T22:14:37+00:00

Allow config variables in .config to override earlier ones in the same
file. In other words,

	# CONFIG_SECURITY is not defined
	CONFIG_SECURITY=y

will activate it. This makes it a bit easier to do

cat original-config myconfig myconfig2 ... >.config;
and run *config as expected.

x86: simplify "make ARCH=x86" and fix kconfig all.config

2007-11-17T16:35:43+00:00

Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
all.config.

For a fix the diffstat is nice:
 6 files changed, 3 insertions(+), 36 deletions(-)

The patch reverts these commits:
 - 0f855aa64b3f63d35a891510cf7db932a435c116 ("kconfig: add helper to set
   config symbol from environment variable")
 - 2a113281f5cd2febbab21a93c8943f8d3eece4d3 ("kconfig: use $K64BIT to
   set 64BIT with all*config targets")

Roman Zippel pointed out that kconfig supported string compares so
the additional complexity introduced by the above two patches were
not needed.

With this patch we have following behaviour:

  # make {allno,allyes,allmod,rand}config [ARCH=...]
  option \ host arch      | 32bit         | 64bit
  =====================================================
  ./.                     | 32bit         | 64bit
  ARCH=x86                | 32bit         | 32bit
  ARCH=i386               | 32bit         | 32bit
  ARCH=x86_64             | 64bit         | 64bit

The general rule are that ARCH= and native architecture takes
precedence over the configuration.

So make ARCH=i386 [whatever] will always build a 32-bit kernel
no matter what the configuration says.  The configuration will
be updated to 32-bit if it was configured to 64-bit and the
other way around.

This behaviour is consistent with previous behaviour so no
suprises here.

make ARCH=x86 will per default result in a 32-bit kernel but as
the only ARCH= value x86 allow the user to select between 32-bit
and 64-bit using menuconfig.

kconfig: add helper to set config symbol from environment variable

2007-11-12T20:02:20+00:00

Add conf_set_env_sym() that can set an already defined symbol
based on the value of an environment variable.

Unknown symbols are silently ignored.
A warning is printed if the value of the environment variable
is unexpected.

kconfig: reset generated values only if Kconfig and .config agree.

2007-07-17T12:24:55+00:00

Normally generated values (Kconfig entries without a prompt) are cleared as
they are regenerated anyway and so they appear as new should they become
visible and defaults work as expected (once a value is set defaults aren't
used anymore).

The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as you
noticed.

The patch now suppresses this logic when .config and Kconfig aren't in sync
and .config needs to be updated, so that you can remove now a random value
from .config and oldconfig won't reask for many other values.
